Description

Technical Field

[0001] This invention relates to the field of cholesterol production technology, and more particularly to a feeding device for cholesterol production. Background Technology

[0002] Cholesterol is a derivative of cyclopentane-polyhydrophenanthrene. Its chemical formula is C27H46O. It is a white or pale yellow crystalline solid and a major steroidal compound in mammals, playing a crucial role in basic cellular life activities. Cholesterol liquid crystal is a special liquid crystal mode with a helical arrangement, a type of organic material display technology. This technology allows for the addition of optically active agents with different rotational pitches to create colors such as red, green, and blue, meeting the needs of color displays.

[0003] In the production of cholesterol, acid and alkali reagents are required. These reagents are added to the production equipment, necessitating a feeding device. Current feeding devices, such as the liquid crystal cholesterol production feeding device shown in authorization announcement number CN21603774603U, include a first storage tank and a second storage tank located to one side of the first storage tank. Both the first and second storage tanks are topped with covers. A set of symmetrically distributed side plates are located on the outer sides of the first and second storage tanks, with a top plate between the two side plates. At the bottom of the top plate are a first electric telescopic rod located on top of the first storage tank and a second electric telescopic rod located on top of the second storage tank. While this design avoids the use of expensive acid and alkali resistant transfer pumps, the addition of acid and alkali reagents can only be controlled by the electric telescopic rods. However, the control and adjustment precision of the electric telescopic rods is low, making it inconvenient to control the feeding speed. Furthermore, after each use, the liquid needs to be pumped out before reuse, resulting in slow replacement speed.

[0004] Furthermore, when feeding acid and alkali solutions, the feeding speed cannot be adaptively adjusted according to the production reaction process, thereby reducing the efficiency of cholesterol production. When the feeding process is accelerated, some acid and alkali solutions will stick to the bottom of the piston and the inside of the storage tank, which will not only reduce the amount of acid and alkali solutions fed, causing some waste of acid and alkali solutions, but also contaminate the subsequent feeding process, thereby reducing the quality of cholesterol production.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0031] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0032] First Embodiment

[0033] Reference Figure 1-5 A feeding device for cholesterol production includes a production cylinder 1. Multiple mounting seats 2 are provided on the side of the production cylinder 1. The mounting seats 2 can be fixed to the surface of the production cylinder 1 by screws or suction cups. Four mounting seats 2 are arranged in a circular array. Each of the four mounting seats 2 has an L-shaped support rod 3 extending to the top of the production cylinder 1. A support base plate 6 is provided on the top of the production cylinder 1. Telescopic support rods 5 are provided on the side of the L-shaped support rods 3 closest to the support base plate 6. The cooperation between the telescopic support rods 5 and the L-shaped support rods 3 allows for adaptation to different sizes of production cylinders 1. One of the telescopic support rods 5 has a display panel 4. The display panel 4 allows for data monitoring of the feeding device and further adjustment of the feeding rate and cleanliness.

[0034] The top of the support base plate 6 is provided with four annular baffles 602 arranged in a ring. Multiple sets of liquid storage cylinders 7 are evenly arranged on the top of the support base plate 6. The outer wall of the liquid storage cylinder 7 is in contact with the inner wall of the annular baffles 602. The annular baffles 602 limit the liquid storage cylinder 7 to ensure the stability of the liquid storage cylinder 7 when it is placed. The inside of the liquid storage cylinder 7 is slidably connected to a ferromagnetic piston plate 21 through the extrusion assembly 8, so that the liquid storage cylinder 7 can discharge material freely or with auxiliary discharge.

[0035] The annular baffle 602 is transparent. The bottom of the supporting base plate 6 is provided with four outlet pipes 603 corresponding to the four annular baffles 602. The outer side of each outlet pipe 603 is provided with a flow meter 606 that is electrically connected to the display panel 4. The flow meter 606 can detect the flow rate of the acid or alkali solution. By connecting to the display panel 4, the amount of material can be displayed in real time, which is convenient for the staff to watch. A U-shaped infusion assembly is connected between two outlet pipes 603 on the same side. At the same time, the storage cylinder 7 connected to the same U-shaped infusion assembly contains the same acid or alkali solution.

[0036] The horizontal part of the L-shaped support rod 3 is hollow. One end of the telescopic support rod 5 slides inside the hollow part of the L-shaped support rod 3, thereby adjusting the position of the telescopic support rod 5. The side of the L-shaped support rod 3 is provided with a limiting bolt to limit the sliding of the telescopic support rod 5. When the limiting bolt rotates on the side of the L-shaped support rod 3, its end abuts against the surface of the telescopic support rod 5, which can form a compression on the telescopic support rod 5, thereby limiting the telescopic support rod 5.

[0037] The telescopic support rod 5 has a placement notch 501 at the end away from the L-shaped support rod 3, and the inner side wall of the placement notch 501 is in contact with the outer side of the support base plate 6, thereby ensuring the stability of the support base plate 6 when it is placed, and also facilitating the installation of the support base plate 6.

[0038] The notch 501 has a positioning bottom hole 502 inside, which is a threaded hole. The support base plate 6 has a positioning top hole 601 through it. Positioning bolts 9 are inserted into the vertically corresponding positioning bottom hole 502 and positioning top hole 601. The positioning bolts 9 can strengthen the positioning connection of the support base plate 6 to ensure the stability of the support base plate 6 during use. At the same time, the positioning bolts 9 can also facilitate the disassembly of the support base plate 6.

[0039] The U-shaped infusion assembly includes a U-shaped connecting pipe 604 that connects two outlet pipes 603 on the same side and an inlet pipe 605 that is connected to the bottom of the U-shaped connecting pipe 604. The inlet pipe 605 is vertically connected to the U-shaped connecting pipe 604, and the bottom end of the inlet pipe 605 extends into the production cylinder 1, so that the two storage cylinders 7 can be transported into the production cylinder 1 through the same inlet pipe 605.

[0040] The extrusion assembly 8 includes a rotating shaft 802 rotatably mounted on the top of the support base plate 6. A motor 801, capable of driving the extrusion assembly 8 to rotate, is located at the center of the bottom of the support base plate 6. The motor 801 can rotate in both directions. The bottom end of the rotating shaft 802 is fixedly connected to the output shaft of the motor 801, thus enabling the motor 801 to drive the rotating shaft 802 to rotate. A four-leaf top plate 803 is located at the top of the rotating shaft 802. Electric telescopic rods 805 are located at opposite ends of the four-leaf top plate 803, arranged diagonally. The bottom of each electric telescopic rod 805 passes through the end of the four-leaf top plate 803 and... The top of the two sets of ferromagnetic piston plates 21 is fixedly connected to the top of the four-leaf top plate 803. The bottom of the two opposite ends of the top plate 803 is provided with connecting pillars 804. The bottom of the connecting pillars 804 is fixedly connected to the top of the other two sets of ferromagnetic piston plates 21. The ferromagnetic piston plates 21 connected to the bottom of the connecting pillars 804 seal the top of the liquid storage cylinder 7 to prevent the acid and alkali liquid from evaporating or being contaminated as much as possible. The ferromagnetic piston plates 21 connected to the bottom of the electric telescopic rod 805 can move up and down inside the liquid storage cylinder 7, thereby accelerating the discharge of acid and alkali liquid in the liquid storage cylinder 7.

[0041] The ferromagnetic piston plate 21 is coaxially arranged with the liquid storage cylinder 7 to realize the piston movement of the ferromagnetic piston plate 21 in the liquid storage cylinder 7, and the ferromagnetic piston plate 21 is inserted into the liquid storage cylinder 7. The ferromagnetic piston plate 21 is equipped with a one-way air inlet valve. The one-way air inlet valve enables the acid and alkali liquid in the liquid storage cylinder 7 to be automatically discharged in small quantities under the action of gravity even when the electric telescopic rod 805 is not extended or retracted.

[0042] The outer wall of the liquid storage cylinder 7 is fitted to the inner wall of the annular baffle 602 to ensure the stable placement of the liquid storage cylinder 7. The bottom end of the liquid storage cylinder 7 is provided with a one-way downward feeding pipe 703 that is inserted into the liquid outlet pipe 603. The top of the outer side of the liquid storage cylinder 7 is provided with a liquid injection pipe 702. The liquid injection pipe 702 is provided to facilitate the addition of liquid after the acid and alkali solutions are used up. The inner wall of the liquid storage cylinder 7 is provided with a side groove, and a liquid level sensor 701 electrically connected to the display panel 4 is provided in the side groove. When the liquid level sensor 701 is installed, it completes the sealing of the side groove to ensure that the extrusion assembly 8 does not affect the discharge when extruding.

[0043] During installation, first, fix the four fixed seats 2 in a circular array and fix them on the top of the outer side of the corresponding production cylinder 1. After installation, adjust the sliding distance of the telescopic support rod 5 from the L-shaped support rod 3 according to the size of the production cylinder 1 so that the support base plate 6 can fit exactly in the four placement notches 501. After adjustment, tighten the limiting bolt. The end of the limiting bolt presses the part of the telescopic support rod 5 that slides in the L-shaped support and limits the telescopic support rod 5. Then, use the positioning bolt 9 to pass through the positioning upper hole 601 and screw it into the positioning bottom hole 502 to complete the installation of the support base plate 6. First, inject acid and alkali solutions into the liquid storage cylinder 7 respectively. After injection, insert the liquid inlet pipe 605 into the production cylinder 1.

[0044] When acid or alkali solutions need to be added, the solutions in the storage cylinder 7 are directly discharged through the bottom single-feed pipe 703 into the outlet pipe 603, and further discharged through the U-shaped connecting pipe 604 and the inlet pipe 605 into the production cylinder 1 for precise feeding. When the feeding speed needs to be increased, the electric telescopic rod 805 is activated. The electric telescopic rod 805 drives the ferromagnetic piston plate 21 downward and squeezes the air in the storage cylinder 7, thereby accelerating the outflow of acid or alkali solutions from the storage cylinder 7. At this time, the liquid level sensor 701 detects the remaining liquid in the storage cylinder 7 in real time. When the acid or alkali solutions in the storage cylinder 7 are used up, the motor 801 is started and rotated 90 degrees. The rotation of the motor 801 drives the rotating shaft 802 to rotate, and the rotation of the rotating shaft 802 drives the four-leaf top plate 803 to rotate 90 degrees, thereby driving the electric telescopic rod 805 and the ferromagnetic piston plate 21 to rotate, so that the electric... The telescopic rod 805 moves to the top of another unused storage cylinder 7. In particular, in order to ensure the accuracy and non-contamination of the ferromagnetic piston plate 21 when discharging the contents of the storage cylinder 7, when the ferromagnetic piston plate 21 at the bottom of the same electric telescopic rod 805 rotates and squeezes the storage cylinder 7 to discharge the contents, the two storage cylinders 7 connected in series by the same U-shaped connecting pipe 604 should be discharged. This will prevent cross-contamination when the ferromagnetic piston plate 21 squeezes and contacts the acid and alkali solutions in the storage cylinder 7 to discharge the contents. Afterwards, the injection pipe 702 injects new acid and alkali solutions into the used storage cylinder 7 and continues to feed the contents. This effectively reduces the downtime for feeding and achieves the continuity and stability of feeding the contents of the production cylinder 1, avoiding the reduction of cholesterol production effect inside the production cylinder 1 due to the cessation of feeding.

[0045] This device effectively enables non-stop feeding during cholesterol production, offering greater selectivity and stability. It also allows for adjustment of the feeding speed based on actual conditions, resulting in better adaptability, simple operation, and precise feeding.

[0046] Second Embodiment

[0047] like Figure 6-9As shown in the first embodiment, when the acid and alkali solutions in the storage tank 7 are fed along the one-way feed pipe 703, the feeding speed cannot be adaptively adjusted according to the production reaction process inside the production cylinder 1, thereby reducing the cholesterol production effect; when the ferromagnetic piston plate 21 squeezes the acid and alkali solutions to accelerate feeding along the storage tank 7, some acid and alkali solutions will stick to the bottom of the ferromagnetic piston plate 21, which will not only corrode the bottom of the ferromagnetic piston plate 21, thereby reducing the durability of the ferromagnetic piston plate 21, but also contaminate the subsequent feeding of acid and alkali solutions in the storage tank 7; and after each feeding of acid and alkali solutions in the storage tank 7 is completed, in order to ensure the subsequent acid and alkali solutions are fed, The stability of alkali feeding requires multiple cleanings of the storage tank 7, which increases labor intensity and reduces the cleanliness of the inside of the storage tank 7. To solve the above problems, the feeding device for cholesterol production also includes: inner grooves 10 are opened on both sides of the storage tank 7 facing each other. The opening position of the two inner grooves 10 is matched with the rotation direction of the ferromagnetic piston plate 21. That is, when the ferromagnetic piston plate 21 rotates forward and backward with the four-leaf top plate 803, it will pass through the top of the inner grooves 10 on both sides, thereby cleaning the bottom of the ferromagnetic piston plate 21 and alternately feeding the two storage tanks 7 at the top of the same U-shaped connecting pipe 604.

[0048] A magnetic sealing block 12 is slidably connected inside the inner tank 10. When the ferromagnetic piston plate 21 moves up and down inside the liquid storage cylinder 7, the magnetic attraction between the ferromagnetic piston plate 21 and the magnetic sealing block 12 drives the magnetic sealing block 12 to move up and down synchronously inside the inner tank 10. Sliding holes 15 are opened on the bottom of the liquid storage cylinder 7 and on the two sides adjacent to the inner tank 10. An opening and closing plate 14 is slidably connected inside the sliding hole 15. When the opening and closing plate 14 opens and closes, it not only adjusts the opening size of the one-way downward feed pipe 703, thereby adjusting the feeding speed of the acid and alkali solution inside the liquid storage cylinder 7, but also, when the opening and closing plate 14 is fully opened, that is, when the distance between the two facing ends of the opening and closing plate 14 reaches its maximum, the opening and closing plate 14 slides into the sliding hole 15. At this time, the bottom of the liquid storage cylinder 7 is flat and the one-way downward feed pipe 703 is in the fully open state. Then the ferromagnetic piston plate 21 moves down continuously and raises the one-way downward feed pipe. The discharge speed is 703. When the ferromagnetic piston plate 21 matches and adheres to the bottom of the liquid storage cylinder 7, the ferromagnetic piston plate 21 moves upward and returns to its original position. At this time, the opening and closing plate 14 moves in the opposite direction along the sliding hole 15, that is, the two opening and closing plates 14 move towards their facing end faces. At this time, the movement of the opening and closing plate 14 is used to scrape and clean the acid and alkali liquid remaining at the bottom of the liquid storage cylinder 7, further improving the cleanliness of the inside of the liquid storage cylinder 7 and reducing the cleaning difficulty for subsequent operators. In particular, when the opening and closing plate 14 moves in the sliding hole 15, the inner top of the sliding hole 15 is used to scrape off the acid and alkali liquid remaining on the top of the opening and closing plate 14. The acid and alkali liquid remaining on the inner wall of the liquid storage cylinder 7 is scraped off by the sliding of the ferromagnetic piston plate 21. Thus, the acid and alkali liquid remaining inside the liquid storage cylinder 7 can be thoroughly and effectively cleaned, with better cleaning effect and higher cleaning efficiency, effectively reducing the labor intensity of subsequent operators.

[0049] Side plates 16 are provided on both sides of the opposite end faces of the two opening and closing plates 14. The side plates 16 serve as connecting components to improve the stability and symmetry of the movement of the opening and closing plates 14. Moving slots 19 are provided at the bottom of the liquid storage cylinder 7 on both sides of the opening and closing plates 14. There are four moving slots 19 in total, evenly distributed on both sides of the two opening and closing plates 14. The end of the moving slot 19 closest to the inner tank 10 is connected to the bottom of the inner tank 10 via a vent 18. Therefore, when the internal air pressure changes in the inner tank 10 due to the movement of the magnetic sealing block 12, the air pressure change in the inner tank 10 is simultaneously transmitted to the moving slot 19 through the vent 18. The internal sliding connection includes a movable block 20. The movable block 20 is provided with a slide rod 17 on the side near the side plate 16. The other side of the slide rod 17 passes through the movable groove 19 and is fixedly connected to one side of the side plate 16. When the air pressure in the movable groove 19 increases and moves the movable block 20 away from the inner groove 10, the movable block 20 moves the side plate 16 away from the inner groove 10 through the slide rod 17. The side plate 16 moves the middle opening and closing plate 14 away from the central axis of the liquid storage cylinder 7. The two opening and closing plates 14 move relative to each other and open. The blockage area of ​​the bottom single downward feed pipe 703 by the two opening and closing plates 14 is reduced, and the feeding speed of the single downward feed pipe 703 is increased.

[0050] A support spring 11 is provided at the bottom of the magnetic sealing block 12. The bottom of the support spring 11 is fixedly connected to the bottom of the inner groove 10. The support spring 11 further improves the stability of the magnetic sealing block 12's reset. In particular, when the ferromagnetic piston plate 21 is not activated and is at the top opening of the liquid storage cylinder 7, the magnetic attraction of the ferromagnetic piston plate 21 on the magnetic sealing block 12 and the elastic force of the support spring 11 make the magnetic sealing block 12 stand at the top of the inner groove 10. At this time, the pressure in the inner groove 10 decreases, and the moving block 20 drives the opening and closing plate 14 to move closer to the center end of the liquid storage cylinder 7. The facing ends of the two opening and closing plates 14 fit together, and the one-way feed pipe 703 is in a closed state. An elastic scraper 13 is provided at the top of the magnetic sealing block 12, and a stop block 22 is provided on the top side wall of the inner groove 10. The stop block 22 and the elastic scraper The peripheral side of plate 13 is matched. The function of the stop block 22 is to limit the movement of the magnetic sealing block 12 in the inner groove 10, so as to prevent the magnetic sealing block 12 from sliding out of the inner groove 10 along the top of the inner groove 10. At the same time, the stop block 22 can also limit and block the elastic scraper 13. When the elastic scraper 13 extends out of the inner groove 10, the bottom of the ferromagnetic piston plate 21 will press against the top of the elastic scraper 13 when the four-leaf top plate 803 rotates. The elasticity of the elastic scraper 13 itself will scrape the bottom of the ferromagnetic piston plate 21. The scraped acid and alkali liquid is returned to the inside of the storage tank 7. This not only achieves the scraping and cleaning of the bottom of the ferromagnetic piston plate 21, avoiding pollution of the acid and alkali liquid in the subsequent storage tank 7, but also recovers the residual acid and alkali liquid adhering to the bottom of the ferromagnetic piston plate 21, avoiding waste of resources.

[0051] In use, after the device is installed according to the first embodiment, the electric telescopic rod 805 is not started. Then, the four ferromagnetic piston plates 21 are all at the top of the liquid storage cylinder 7. Acid and alkali solutions are added into the liquid storage cylinder 7 along the injection pipe 702. In particular, in order to ensure the stability and efficiency of feeding, the same acid and alkali solutions are added to the two liquid storage cylinders 7 connected at the top of the same U-shaped connecting pipe 604, while different acid and alkali solutions are added to the two liquid storage cylinders 7 connected at the top of different U-shaped connecting pipes 604. This achieves the effect of feeding without stopping the device and feeding multiple raw materials simultaneously.

[0052] After the addition is completed, under the magnetic attraction of the ferromagnetic piston plate 21 to the magnetic sealing block 12 and the elastic force of the supporting spring 11, the ferromagnetic piston plate 21 is located at the top of the inner groove 10 and in contact with the bottom of the stop block 22. At this time, the volume of the inner groove 10 is the largest and the corresponding pressure is the smallest. The bottom of the inner groove 10 applies a suction force to the moving groove 19 through the vent 18. The moving block 20 in the moving groove 19 moves towards the end of the inner groove 10. When the moving block 20 moves, it drives the side plate 16 to move towards the end of the inner groove 10 through the slide rod 17. The two sets of opening and closing plates 14 move towards the opposite end and stick to each other. At this time, the two sets of opening and closing plates 14 block the one-way downward feed pipe 703 at the bottom of the liquid storage cylinder 7. The flow rate detected by the flow meter 606 is zero, thereby preventing the acid and alkali liquid in the liquid storage cylinder 7 from being discharged along the one-way downward feed pipe 703.

[0053] When it is necessary to feed the acid and alkali solutions in the storage tank 7 into the production tank 1, the display panel 4 controls the two sets of electric telescopic rods 805 to start respectively. The output end of the bottom of the electric telescopic rod 805 drives the corresponding ferromagnetic piston plate 21 to move downward along the inner wall of the storage tank 7. When the ferromagnetic piston plate 21 moves downward, it drives the magnetic sealing block 12 to move downward along the inner groove 10 by means of the magnetic attraction force on the magnetic sealing block 12. As a result, the volume in the inner groove 10 decreases and the pressure increases. The gas in the inner groove 10 flows into the moving groove 19 along the ventilation channel 18. The moving block 20 in the moving groove 19 moves away from the inner groove 10 under the action of air pressure. When the moving block 20 moves, it drives the side plate 16 to move away from the inner groove 10 in sync through the slide rod 17. When the two sets of side plates 16 move, they drive the middle opening and closing plate 14 to move away from the storage tank 7. As the central axis moves, the facing ends of the two opening and closing plates 14 move away from each other, and the blocking area of ​​the opening and closing plates 14 on the one-way downward feed pipe 703 at the bottom of the liquid storage cylinder 7 gradually decreases. The flow rate of the acid and alkali liquid in the liquid storage cylinder 7 along the one-way downward feed pipe 703 to the outlet pipe 603 gradually increases, and the flow rate value detected by the flow meter 606 gradually increases. When the flow rate value detected by the flow meter 606 reaches the preset flow rate value, the bottom output end of the electric telescopic rod 805 controlled by the display panel 4 stops descending, and the ferromagnetic piston plate 21 stops moving downward along the inner wall of the liquid storage cylinder 7. Under the action of the one-way air inlet valve at the top of the ferromagnetic piston plate 21, the acid and alkali liquid in the liquid storage cylinder 7 is stably fed along the one-way downward feed pipe 703 and reaches the outlet pipe 603 along the one-way downward feed pipe 703, and finally discharged into the production cylinder 1 along the U-shaped connecting pipe 604 and the inlet pipe 605.

[0054] When the flow rate detected by the flow meter 606 is less than the preset flow rate value, the display panel 4 only needs to control the electric telescopic rod 805 to move downward. The electric telescopic rod 805 then drives the ferromagnetic piston plate 21 to move downward. Through the above process, the opening and closing plate 14 opens and moves to both sides, thereby increasing the distance between the two opening and closing plates 14 facing each other. The opening degree of the single downward feed pipe 703 increases, and the speed at which the acid and alkali solutions in the storage tank 7 are fed along the single downward feed pipe 703 increases.

[0055] In particular, when the ferromagnetic piston plate 21 moves downward along the liquid storage cylinder 7, the ferromagnetic piston plate 21 is in a sealed sliding connection with the inner wall of the liquid storage cylinder 7, thereby scraping off the acid and alkali liquid remaining on the inner wall of the liquid storage cylinder 7 by the peripheral side of the ferromagnetic piston plate 21. When the opening and closing plate 14 moves along the sliding hole 15, the top of the inner wall of the sliding hole 15 scrapes off the acid and alkali liquid remaining on the top of the opening and closing plate 14, further improving the cleanliness of the liquid storage cylinder 7 and the utilization rate of the acid and alkali liquid.

[0056] When the electric telescopic rod 805 drives the ferromagnetic piston plate 21 to move downward along the liquid storage cylinder 7 to the set distance, the ferromagnetic piston plate 21, through the magnetic attraction with the magnetic sealing block 12, drives the magnetic sealing block 12 to squeeze the support spring 11 downward to the set height. Through the above process, the distance between the facing end faces of the two sets of opening and closing plates 14 reaches the set preset value, and the two sets of opening and closing plates 14 no longer block the single downward material pipe 703, and the feeding speed of the single downward material pipe 703 reaches the maximum value.

[0057] If the flow rate detected by the flow meter 606 is still less than the preset flow rate value, then the rate at which the acid and alkali solutions in the storage tank 7 are fed along the one-way downward feed pipe 703 by atmospheric pressure alone is insufficient to meet the production requirements of cholesterol in the production cylinder 1. At this time, the bottom output end of the electric telescopic rod 805 controlled by the display panel 4 moves further downward. When the electric telescopic rod 805 moves downward, it simultaneously drives the bottom ferromagnetic piston plate 21 to move downward. The ferromagnetic piston plate 21 moves downward along the storage tank 7 and increases the pressure inside the storage tank 7. Then, with the help of the air pressure inside the storage tank 7, the feeding speed of the acid and alkali solutions in the storage tank 7 along the one-way downward feed pipe 703 is further increased, and the flow rate detected by the flow meter 606 meets the preset flow rate value. As the ferromagnetic piston plate 21 moves downward along the storage tank 7... During movement, the ferromagnetic piston plate 21, through the magnetic attraction of the magnetic sealing block 12, causes the magnetic sealing block 12 to compress the support spring 11 downward and move downward. The volume of the inner groove 10 decreases and the pressure increases. The air pressure in the inner groove 10 flows into the moving groove 19 along the vent 18. The moving block 20 in the moving groove 19 moves away from the inner groove 10. When the moving block 20 moves, it drives the side plate 16 to move away from the inner groove 10 to the maximum value through the slide rod 17. The two side plates 16 drive the middle opening and closing plate 14 to move away from the central axis of the liquid storage cylinder 7 to the maximum distance. At this time, the opening and closing plate 14 is completely retracted into the sliding hole 15 and matches the end of the sliding hole 15. The inner top of the sliding hole 15 is used to thoroughly and effectively scrape away the acid and alkali liquid remaining on the top of the opening and closing plate 14, further improving the cleanliness and stability of the opening and closing plate 14.

[0058] Simultaneously, the ferromagnetic piston plate 21 moves downward along the storage cylinder 7 to its maximum distance and contacts the bottom of the storage cylinder 7. All the acid and alkali solutions in the storage cylinder 7 are then quickly and efficiently discharged through the one-way downward feed pipe 703. After the storage cylinder 7 is filled, the display panel 4 controls the bottom output end of the electric telescopic rod 805 to move upward. The electric telescopic rod 805 then drives the bottom ferromagnetic piston plate 21 upward. Under the magnetic attraction of the ferromagnetic piston plate 21 to the magnetic sealing block 12 and the elastic force of the supporting spring 11, the magnetic sealing block 12 moves upward along the inner groove 10. The volume in the inner groove 10 increases and the pressure decreases. The corresponding two sets of opening and closing plates 14 move towards their facing end faces and come into contact. When the opening and closing plates 14 move to the bottom of the storage cylinder 7, they scrape off the acid and alkali solutions remaining at the bottom of the storage cylinder 7. The scraped acid and alkali solutions are then discharged through the one-way downward feed pipe 703. This not only achieves the cleanliness and stability of the storage cylinder 7 but also further improves the utilization of the acid and alkali solutions, avoiding some waste.

[0059] When the ferromagnetic piston plate 21 moves upward to its initial position, the magnetic sealing block 12 moves upward to its initial position and comes into contact with the bottom of the stop block 22. The elastic scraper 13 at the top of the magnetic sealing block 12 extends out of the inner groove 10 between the stop blocks 22. The display panel 4 controls the motor 801 to start and drives the four-leaf top plate 803 to rotate 90 degrees in the forward direction through the rotating shaft 802. The four-leaf top plate 803 then drives the bottom ferromagnetic piston plate 21 to rotate 90 degrees in the forward direction. At this time, the ferromagnetic piston plate 21 at the bottom of the electric telescopic rod 805 is facing the top of the liquid storage cylinder 7 connected to the top of the same U-shaped connecting pipe 604 for subsequent feeding. In particular, when the ferromagnetic piston plate 21 rotates, the bottom and the top of the elastic scraper 13 squeeze and scrape against each other, thereby effectively scraping and cleaning the acid and alkali liquid remaining at the bottom of the ferromagnetic piston plate 21, improving the cleanliness of the ferromagnetic piston plate 21 and avoiding the acid and alkali liquid remaining at the bottom of the ferromagnetic piston plate 21 from affecting the subsequent feeding.

[0060] When the ferromagnetic piston plate 21 at the bottom of the electric telescopic rod 805 reaches the top of the other storage cylinder 7, the above process is repeated to feed the acid and alkali solutions into the storage cylinder 7. After the storage cylinder 7 has been fed, the solution is added again through the injection pipe 702. That is, after the other storage cylinder 7 has been fed, the display panel 4 controls the motor 801 to rotate 90 degrees in the opposite direction and drives the four-leaf top plate 803 to rotate 90 degrees in the opposite direction through the rotating shaft 802. Then the ferromagnetic piston plate 21 at the bottom of the electric telescopic rod 805 rotates again to the top of the storage cylinder 7 that has been filled with acid and alkali raw materials, and the above process is repeated to feed the acid and alkali solutions into the storage cylinder 7. After the feeding is completed, the device can be removed by reversing the above process.

[0061] This device boasts high installation efficiency and excellent installation results. It can also adaptively adjust the opening size of the unidirectional feed pipe 703, thereby adaptively adjusting the feeding speed, resulting in greater adaptability and simpler operation. Even when the opening of the unidirectional feed pipe 703 reaches its maximum, it can further increase the feeding speed of the acid and alkali solutions in the storage tank 7, and scrape and clean the residual acid and alkali solutions inside the storage tank 7 and at the bottom of the ferromagnetic piston plate 21, further improving the cleanliness and stability of the device. It is energy-saving, environmentally friendly, and promotes green emission reduction.
